* input: implement follow_mouse_shrink
Add a new config option `input:follow_mouse_shrink` (INT, 0-300, default 0)
that shrinks inactive window hitboxes by the specified number of pixels for
focus detection purposes. This creates a dead zone in gaps between windows
where moving the cursor will not trigger a focus change.
The shrink only applies to inactive (non-focused) windows and only during
mouse-move focus checks (follow_mouse = 1). Click and scroll interactions
are unaffected — clicking on a window in the shrunk area still works
normally once the window is focused.
Closes#9973
* tests: add integration test for follow_mouse_shrink
* Add test for movewindowgroup
* groups: Fix `movewindoworgroup` moving into group
Fixes `CKeybindManager::moveWindowIntoGroup` to
remove a window from a group before attempting
to add it to another group. Addresses #13843.
But the animation of moving a window from a group
into another group now looks weird: as if the
whole target group is being moved.
* xwayland: prefer monitor-aware hover coords
Introduce monitor-aware XWayland coordinate helpers and keep the X11 hover path anchored to the main surface box while preserving detailed debug logging, reducing dependence on nearest-monitor guesses in layout-sensitive input paths.
* xwayland: use window monitor for reported coords
Report X11 window positions through the window's known monitor instead of the generic nearest-monitor heuristic so boundary-aligned outputs keep stable XWayland coordinates.
* xwayland: use window monitor for real position restore
Convert XWayland geometry back into compositor space using the window's current monitor when available so vertically offset layouts do not round-trip through the wrong output.
* xwayland: use window monitor for unmanaged geometry
Restore override-redirect X11 geometry through the window's known monitor so helper windows and popups avoid nearest-monitor misclassification on offset layouts.
* xwayland: remove monitor conversion debug logging
Drop the temporary XWayland hover and coordinate conversion diagnostics now that the monitor-selection bug is confirmed and the window-monitor based conversions fix the issue.
* xwayland: drop unrelated focused-motion change
Remove the exploratory X11-specific pointer focus scaling from InputManager so the monitor mapping fix stays narrowly scoped to the XWayland coordinate conversion changes that actually resolve the bug.
* clang-format XWaylandManager
* misc: silence warnings about ignoring return value on reads
silence warnings on ignored return values on read() and print an error
if it occurs.
* misc: silence warnings about ignoring return value on writes
silence warnings on ignored return values on write() and print an error
where we can, or pass them the maybe_unused attribute.
* misc: silence warnings about ignoring return value on pipe
silence warnings on ignored return value on pipe(), print an error and
exit on failure.
There seems to be no reason for them to remain.
But if they are kept, no notification appears to warn
a user that a dispatcher used in their config is no
longer valid. The config remains valid, but the bindings
do not work anymore.
